However, you need to be very careful with this as calculations are
being done assuming a spherical earth. Fine is distances arent large
enough for the ellipsoidal effects to affect accuracy. For large
distances, you need to use Vincent' s_formula -
<a class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/Vincenty%27s_formulae">http://en.wikipedia.org/wiki/Vincenty%27s_formulae</a> which require
iteration.<br>
